3 cards from this section. Quick, good the night before a test.
What does exponential decay refer to?
Think about how quickly things lose value.
If a car depreciates at 10% per year and is worth $10,000 initially, what will it be worth after one year?
Calculate 10% of $10,000 and subtract from the original value.
What does the term 'exponential decay' refer to?
Think about what happens when something loses value.
True or False: If a quantity decays exponentially, it will eventually reach zero.
Visualize what happens to a curve approaching the axis.
A piece of machinery loses value at a rate of 30% per year. If its initial cost was $200,000, what will its value be after 3 years?
Don’t forget to calculate each year's reduction to find the final value.
Explain how different decay rates affect the value of an item over time, using a graph to show your findings.
Consider drawing graphs for 10% vs. 25% decay for clear comparison.
